Hi All,

Help, I'm seem to have an issue withe my DSS Setup.

I have 2 DSS machines in a fail over configuration.

Since upgrading to ESXi 5.0.0 I've had nothing but issues with I/O.
My environment was running smooth on ESXi 4.1 but since upgrading to 5.0.0 I'm having some very bad latency issues.

I have 6 Ethernet ports in each of my DSS SANS.
eth0 = management port (purely web interface etc)
eth1 -> directly connected to eth1 on SAN2 (this is my replication nic)
eth2 through eth5 are shared across 2 switches.
eth2 - eth4 go to switch 1, eth3, eth5 go to switch 2.

My switches are connected via a 4 port trunk/lacp.

I think the issue I'm having is with the replication slowing down things, if I shutdown my passive node the I/O seems to stabilize and I don't have an issue. But when in full failover configuration I get degraded (border line VM guests dying I/O).
I have a 4 node server as my VM host with only around 36-40 VM's.

Does any one have advise on tracking down whats going on. The graphs don't show much traffic at all over the replication port.

Cheers
Adam
